Proceedings of a NATO ARW held in Maratea, Italy, July 2-8, 1989
A NATO Advanced Research Workshop was held on the topic of the possible roles and regulation of serine proteases and their high molecular weight inhibitors, the serpins, in the nervous system. Some of the topics covered in this workshop include: Biochemistry and cell biology; Thrombin structural regions in determining bioregulatory functions; Main components of the fibrinolytic system (i.e. plasmin); Inhibitors of the fibrinolytic system; Regulation and control of physiological fibrinolysis; A key molecule dictating and regulating surface plasmin formation; Regulation of tissue plasminogen activator secretion from human endothelial cells, Thrombin disintegrates cell surface urokinase focal adhesion plaques and decreases cell extension; The heparin binding site and activation of protease nexin 1; Peptide hydrolases; Fibroblasts accelerate the inactivation of thrombin by PNI; Fibroblasts block the ability of PNI to inactivate urokinase and plasmin; Use of protein chemistry and molecular biology to determine interaction areas between proteases and their inhibitors; Signal transduction chains involved in the control of the fibrinolytic enzyme cascade; Structure of the human protease nexin gene and expression of recombinant forms of PNI; Serine proteases in the nervous system; and Serpins in degenerative and malignant neurologic diseases.
The book provides an comprehensive overview on biology, genetics and cellular functions of serpins (serine protease inhibitors) in health and disease. With over 1000 members serpins are the most diverse family of protease inhibitors. Latest groundbreaking research findings are presented and broaden the understanding on inhibitory and non-inhibitory serpins, not only in mammalian organisms but also in insects, worms, plants and viruses.​
This book bridges the gap between fundamental research and biomedical and pharmacological applications on proteases. It represents a comprehensive overview of the multifaceted field of proteases in cellular environment and highlights the recently elucidated functions of complex proteolytic systems in different diseases. Several established investigators have elucidated the crucial role of proteases in biological processes, including how proteolytic function and regulation can be combined to develop new strategies of therapeutic interventions. Proteases form one of the largest and most diverse families of enzymes known. It is now clear that proteases are involved in every aspect of life functions of an organism. Under physiological conditions, proteases are regulated by their endogenous inhibitors; however, when the activity of proteases is not regulated appropriately, disease processes can result in. So, there is absolute need for a stringent control of proteolytic activities in cells and tissues. Dysregulation of proteases may cause derangement of cellular signalling network resulting in different pathophysiological conditions such as vascular remodelling, atherosclerotic plaque progression, ulcer and rheumatoid arthritis, Alzheimer disease, cancer metastasis, tumor progression and inflammation. Additionally, many infective microorganisms require proteases for replication or use proteases as virulence factors, which have facilitated the development of protease-targeted therapies for a variety of parasitic diseases.
First multi-year cumulation covers six years: 1965-70.
This book will give an overview on viruses undergoing proteolytic activation through host proteases. The chapters will be organized in three themed parts, the first part describing respective viruses and their characteristics in detail. In the second part the molecular and cellular biology of the proteases involved as well as their physiological functions will be further explored. The third part will contain a chapter on protease inhibitors that are promising tools for antiviral therapy. This book will engage scholars in virology and medical microbiology as well as researchers with an interest in enzymology and protein structure and function relationship.
